Despite wearing a price tag of just under $300,000 before on-road costs, Porsche's allocation of 40 911 GT3 models in 2014 is all but sold out.

That still leaves plenty of cashed-up enthusiasts who won’t get the opportunity to strap into one of the word’s most revered high-performance machines that lays claim to being equally at home on the track as it is on the road.

The news isn’t any better for 2015, according to Porsche Australia’s director of public relations and motorsport, Paul Ellis, who told CarAdvice that next year’s initial allocation will not be sufficient to meet demand for the GT3.

“Traditionally the GT3 has been a very strong seller in this market; I think we’re probably one of the biggest markets in terms of 911 GT road cars with the likes of GT3, GT3 RS, GT2 RS in relatively high demand," he said.

"Australia is known internationally as the ‘enthusiasts market’, so we have a very devoted customer base for these types of 911 GT road cars, but we’ve never been in a position to match supply with demand.

“Next year we have allocation, but we’ve asked for that to be doubled," he added.

The latest Porsche 911 GT3 is a new-generation car based on the current 991 chassis and benefits from significant technical highlights including a new direct injection 3.8-litre flat six that produces 350kW of power and 440Nm of torque.

Whereas the previous engine in the 997 GT3 11 would rev out to 8500rpm, the new version will spin out at a dizzying 9000rpm.

It will accelerate from zero to 100km/h in 3.5 seconds and tops out at 315km/h.

The previous manual transmission has been replaced by Porsche’s seven-speed dual-clutch (PDK) gearbox coming as standard fitment in the GT3, with no manual option. That makes it the first two-pedal Porsche 911 GT road car.

The new GT3 also gets the same electrically assisted steering as the rest of the 911 lineup.

There’s also new software and a stiffened-up front end, while the rear of the car gets an active rear-steer system. At low speeds it turns the wheels in the opposite direction to the fronts, while at higher speeds they turn in the same direction for improved agility and response rates.
